Why is it that after god gives someone a disease or genetic defect and it takes a team of doctors and surgeons with millions of dollars in equipment and decades of combined training to fix it, people say its a miracle and thank god?

Well strict christian believers will tell you that all talent is God given (even yours) and that the developments that allow Doctors to perform difficult surgery to save lives is a result of Gods gifts.
I find it interesting that some people die from the most insignificant injuries while some people that should be dead (after being in horrific accidents, trapped in machinery, etc ) are walking around with no sign of their previous injuries.
